HI,
Check the current memory by Router#show mem su but is suggest that the
problem is due to sometimes the CPU get higher due to virus attacks whichis
filtered by your ACL so the ACL consume the router CPU which lead the box to
hangup anyway monitor your router for one day and check the cause of the
problem.
Best Reagrds,
